Wow! The Leyden at 87%, It's going to be interesting what other manufactures come up with and how they perform these tests to qualify for the tax rebate.

Woodstock mentioned a 91.x% efficiency number when I ordered my second Fireview last week.

How can this be, there has to be enough heat left over for chimney draft.

You've described one difference between North American "High Heat Value" testing and European "Low Heat Value" testing. In Low Heat Value testing, a portion of the heat value of the test load is considered unavailable for transmission to the room, because it is needed to maintain chimney updraft and to prevent creosote condensation. Since this heat value is out of the picture from the get-go, the stove being tested isn't penalized for not delivering it.
The IRS is expected to approve Low Heat Value testing within a few days, for purposes of the 30% tax credit. Very soon thereafter, you'll see an industry-wide barrage of higher efficiency numbers for wood stoves similar to those published by Travis Industries.
And get used to the new numbers. It is expected by every hearth product industry member I've spoken to that Low Heat Value testing will remain the new North American testing standard after the tax credit period expires.

That makes WAY too much sense. It'll never happen. :smirk:
